Castle Sneak Peek: Can Beckett Save Castle?

Beckett had just said yes to his marriage proposal, and aside from some pesky work details (such as turning up at her crime scenes) the DC job wasn’t looking so intimidating after all.

But after a series of events played out in Castle’s season premiere last week, Rick discovered he was poisoned with a deadly toxin during his brief kidnapping ordeal at the hands of a paranoid government agent.

What is Valkyrie? How is it linked to Beckett’s case, and does Rick really only have 24 hours to live?

Check out this sneak peek from Sunday’s upcoming Castle 6×02 episode “Dreamworld” along with ABC’s latest press release for the episode below.
